You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

You are evaluating a software engineering task for repository rigetticomputing/pyquil. Problem Statement: Unequal length PauliSums raise a warning rather than warn If two `PauliTerms` are compared with unequal lengths they raise a warning which breaks the control flow- it should just warn the user. ## Task Budget (Session terminates when any budget is exhausted) - Time allowance: 7.5 minutes - Tool calls allowance: 30 calls - Max loop iterations: 40 turns ## Execution Environment Rules - Single command timeout: 90 seconds (commands exceeding this fail without ending the session) - Command output limit: 5000 characters - File view limit: 150 lines per read_file call - File character limit: 10000 characters per read_file call - Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages. ## Instructions: 0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages. 1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules. 2. Inspect existing codebase conventions and test files before making edits. 3. Verify your implementation using targeted tests or inline assertions before submitting. 4. Call submit_patch only after your implementation is complete and verified. 5. As your final action, you must return a text-only response reporting your completion to terminate the session. ## Workspace Layout The repository is located at `/workspace`. Here is the directory tree (up to 3 levels): ``` ./ACKNOWLEDGEMENTS.md ./LICENSE ./NOTICE ./README.md ./docs ./examples ./pyquil ./pyquil/__init__.py ./pyquil/api.py ./pyquil/gates.py ./pyquil/job_results.py ./pyquil/parametric.py ./pyquil/paulis.py ./pyquil/plots.py ./pyquil/qpu.py ./pyquil/quil.py ./pyquil/quil_atom.py ./pyquil/quilbase.py ./pyquil/resource_manager.py ./pyquil/setup ./pyquil/setup/__init__.py ./pyquil/setup/config.py ./pyquil/slot.py ./pyquil/tests ./pyquil/tests/data ./pyquil/tests/test_forest.py ./pyquil/tests/test_job_results.py ./pyquil/tests/test_parametric.py ./pyquil/tests/test_paulis.py ./pyquil/tests/test_qpu.py ./pyquil/tests/test_quil.py ./pyquil/tests/test_resource_manager.py ./pyquil/tests/test_wavefunction.py ./pyquil/wavefunction.py ./requirements.txt ./setup.cfg ./setup.py ./tox.ini ```

The problem statement says "Unequal length PauliSums raise a warning rather than warn". Wait, the exact phrasing is: "If two `PauliTerms` are compared with unequal lengths they raise a warning which breaks the control flow- it should just warn the user."
Wait, "raise a warning"? In Python, `warnings.warn()` doesn't typically "break the control flow" unless the warnings are configured to be raised as exceptions (e.g., via `warnings.simplefilter('error')`).
However, if the code is actually calling `raise` with a warning-like exception, or if it's calling something that triggers a `UserWarning` that the system is configured to treat as an error, that would break control flow.
Let's look for `PauliSum` or `PauliTerm` in the code. They are likely in `pyquil/paulis.py`.
Looking at the workspace layout, `pyquil/paulis.py` is the most likely location.
And there's `pyquil/tests/test_paulis.py`.
Let's start by searching for `PauliSum` and `PauliTerm` and any mentions of "warning" or "raise" in `pyquil/paulis.py`.

The reproduction confirms that `UnequalLengthWarning` is raised as an exception.
The fix should be to use `warnings.warn(UnequalLengthWarning("..."))` instead of `raise UnequalLengthWarning("...")`.
Wait, `warnings.warn` takes the category as a separate argument if you want to specify it.
The common usage is `warnings.warn("message", category=WarningCategory)`.
Let's check how `warnings.warn` is used in the codebase, if at all.

The reproduction confirms that `UnequalLengthWarning` is raised as an exception.
The fix should be to use `warnings.warn(UnequalLengthWarning("..."))` instead of `raise UnequalLengthWarning("...")`.
Wait, `warnings.warn` takes the category as a separate argument if you want to specify it.
The common usage is `warnings.warn("message", category=WarningCategory)`.
Let's check how `warnings.warn` is used in the codebase, if at all.

It's not imported. I'll need to import it.
Wait, before I fix it, I want to make sure I'm doing it the right way.
The problem says "raise a warning rather than warn". This is slightly confusing phrasing, but the context "which breaks the control flow" makes it clear that `raise` was used when `warnings.warn` was intended.
Let's modify `pyquil/paulis.py`.
I need to:
1. Add `import warnings` at the top of the file.
2. Replace `raise UnequalLengthWarning("These PauliSums have a different number of terms.")` with `warnings.warn("These PauliSums have a different number of terms.", UnequalLengthWarning)`.

______________________________ test_sum_equality ______________________________ own

assert pauli_sum != pauli_sum + sZ(0)
E Failed: DID NOT RAISE <class 'pyquil.paulis.UnequalLengthWarning'>
```
Wait, if the test is:
```python
assert pauli_sum != pauli_sum + sZ(0)
```
No, wait. The error message "Failed: DID NOT RAISE <class 'pyquil.paulis.UnequalLengthWarning'>" sounds like it was using `pytest.raises(UnequalLengthWarning)`.
Let me read that test.

Wow, the existing tests are literally testing that it RAISES a warning as an exception!
```python
with pytest.raises(UnequalLengthWarning):
assert pauli_sum != pauli_sum + sZ(0)
with pytest.raises(UnequalLengthWarning):
assert pauli_sum + sZ(0) != pauli_sum
```
Since the problem statement says "Unequal length PauliSums raise a warning rather than warn... it should just warn the user", the tests are actually wrong according to the desired behavior.
HOWEVER, the "Protected Grading Paths" rule says:
"Before running official verification, the grading harness strips and reverts all changes to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files."
Wait, if I can't change the tests, and the tests expect an exception, then my fix will always fail the tests.
But the task is to fix the bug. The bug is that it raises instead of warns.
Wait, if the grader reverts changes to `tests/`, then I *cannot* fix the tests. But if the tests are still there, they will fail.
Let me re-read the "Protected Grading Paths" rule.
"Before running official verification, the grading harness strips and reverts all changes to `tests/`... Every part of your fix MUST reside in non-test production source files."
This means I should NOT change the tests. If the tests fail after my fix, it might be that the grader uses a different set of tests, or the tests are also considered "buggy" and the grader knows that.
Wait, usually, in these environments, the tests provided *are* the baseline. If the baseline tests are wrong, then the problem is more complex.
But let's look at the wording: "If two `PauliTerms` are compared with unequal lengths they raise a warning which breaks the control flow- it should just warn the user."
Wait, actually the issue description says `PauliTerms` but the code showed it's `PauliSum`.
Let's look at `PauliTerm.__eq__` again.
```python
def __eq__(self, other):
if not isinstance(other, (PauliTerm, PauliSum)):
raise TypeError("Can't compare PauliTerm with object of type {}.".format(type(other)))
elif isinstance(other, PauliSum):
return other == self
else:
return self.id() == other.id() and np.isclose(self.coefficient, other.coefficient)
```
If `other` is a `PauliSum`, it calls `other == self`. `other` is a `PauliSum`, so it calls `PauliSum.__eq__(self, other=PauliTerm)`.
In `PauliSum.__eq__`:
```python
elif isinstance(other, PauliTerm):
return self == PauliSum(other)
```
This creates a new `PauliSum` from the `PauliTerm`. Then it compares two `PauliSum`s. If they have different lengths, it raises `UnequalLengthWarning`.
So it affects both `PauliTerm` and `PauliSum` comparisons.
Now, about the tests. If the tests expect the exception, and I change it to a warning, the tests will fail.
But I am instructed: "Every part of your fix MUST reside in non-test production source files."
If I can't fix the tests, then I'm at a deadlock. UNLESS the grading harness uses a *different* set of tests for the final evaluation, or it's okay that the provided tests fail as long as the production code is correct.
However, "pass every hidden fail-to-pass and pass-to-pass regression test on the first grading run".
If the provided tests are part of the regression tests, they must pass.
Wait, "The grading harness strips and reverts all changes to `tests/`". This means any changes I make to `tests/` are ignored. It doesn't say that the tests are replaced by something else. It says they are reverted.
If the tests expect the exception, then the only way to make them pass while still "warning instead of raising" is to... wait, you can't. A warning is not an exception.
Maybe I should check if there is a way to make `warnings.warn` raise an exception only in tests? No, that's not how it works.
Let's think. If the task is to "warn rather than raise", then the test that asserts it raises IS wrong.
Is it possible that `UnequalLengthWarning` is not just a `Warning` but something that's intended to be caught? No, the problem says "it should just warn the user".
Let me double check the reproduction again.
Original code:
```python
elif len(self.terms) != len(other.terms):
raise UnequalLengthWarning("These PauliSums have a different number of terms.")
return False
```
Current code:
```python
elif len(self.terms) != len(other.terms):
warnings.warn("These PauliSums have a different number of terms.", UnequalLengthWarning)
return False
```
If I want the tests to pass AND follow the problem statement, there's a contradiction.
Wait! "If two `PauliTerms` are compared with unequal lengths they raise a warning".
Maybe it's not supposed to be `warnings.warn`, but something else? No, "should just warn the user" almost always means `warnings.warn`.
Let me re-read the issue one more time.
"If two `PauliTerms` are compared with unequal lengths they raise a warning which breaks the control flow- it should just warn the user."
Is it possible that the user meant that it should return `False` and NOT raise anything? Yes, that's what my fix does.
Wait, maybe I should use `warnings.warn` but the tests should be updated to use `pytest.warns` instead of `pytest.raises`? But I can't update the tests.
Let me check if there is any other way to "warn" in Python that might still be "raised"? No.
Could it be that `UnequalLengthWarning` should be a `UserWarning` and not just `Warning`? No, that doesn't change whether it's raised or warned.
Let me search for other occurrences of `pytest.raises(UnequalLengthWarning)` in the whole repository.
